Volcano Mountain is a small cinder cone in central Yukon Territory, Canada, near the confluence of the Pelly and Yukon Rivers. The lava at Volcano Mountain is called olivine nephelinite which is a very uncommon type of lava. This type of lava is believed to have come from much deeper inside the Earth than the basaltic lava. The last eruption from Volcano Mountain produced young nephelinitic lava flows that remain unvegetated and appear to be only a few hundred years old.
[edit] Hazards of Volcano Mountain
Future eruptions from Volcano Mountain would probably be lava flows, since there is a lack of pyroclastic material. The main hazards from Volcano Mountain are forest fires started by the lava flows. Older volcanic deposits south of Volcano Mountain, indicates that lava flows may have once partly blocked or at least altered the course of the Yukon and Pelly River. Any future activity in this area could disrupt the course of both of these major rivers and could have a serious impacts on people living or working downstream.
